Frequently Ask Questions
A Rising Stem Gate Valve is a gate valve in which the stem moves upward as the valve opens and downward as it closes.
The movement of the stem provides a visible indication of the valve's open or closed position.
OS&Y means Outside Screw and Yoke.
In this arrangement, the operating screw/stem mechanism is outside the valve body and the stem moves vertically during operation.
It depends on the application.
Rising Stem: Better where visual valve-position indication and easy maintenance are important.
Non-Rising Stem: Better where vertical installation space is limited, particularly underground.
The primary advantage is clear visual indication of valve position. Operators can see whether the valve is open or closed by observing the stem position.
When the handwheel is rotated:
The stem moves upward → Valve opens
The stem moves downward → Valve closes
The gate/wedge moves with the stem to open or block the flow passage.
